This thread is very old but I'm replying just in case since I'm working on this family.
I have noticed that Simeon Webber Adams married Tryphena Edmonds in Chard. I have no idea where the "Adams" came from, or went to later. It may have been a recording error but I am waiting for some certificate copies to dig deeper. There may have been more than one Simeon Webber family, too, as the one in the 1861 census is probably not the same one.
